PLOW.

SPECIFICATION forming part of Letters Patent No. 596,372, dated December28, 1897. Application filed June 15, 1897. Serial No. 640,852. (Nomodel.)

' tion, reference being had to the accompanyin g drawings.

The special objects of the present improvements are to render the plowlight and strong and easyrunning, reducing the effort required by theplowman to handle the plow to a minimum, and to render the handles andbeam and plow-plate readily adjustable as regards pitch and height, asmore fully hereinafter set forth.

Referring to the drawings, Figure 1 is a side elevation of the plowcomplete, a part being broken away to show the adj ustability of theplow-plate; Fig. 2,.a plan view thereof;

Fig. 3, arear view of the stock detached, and Fig. 4 a rear view of theplow-plate detached.

Referring to the drawings by letter, a designates the foot or frontstandard of the stock, I) the foot-bar, which extends rearward from thelower end of the foot a, c the rear standard connecting the rear end ofbar I) to an upper connecting-bar d, and e an arched brace connectingthe bar d to the standard 0 about midway the length of said bar andstandard, these several parts being cast integral and forming a strongskeleton stock. Cast integral with the upper end of the foot part a area pair of plates f, which extend upward and embrace the beam g, andextending through the plates and beam is a horizontal pivot-bolt f. Castintegral with the stock at the upper end of rear standard 0 are a pairof upward-extending plates h, which embrace the beam at a point asuitable distance to the rear of pivot f, these plates being providedwith coincident holes through which and a suitable hole in the beam aremovable eyebolt or pin is passed, this arrangement permitting the beamto be elevated or depressed at its rear end. Pivoted on op posite sidesof the stock at the upper end of the rear standard are the handles 2',beveled lugs j being formed on the stock to serve as bearings for thehandles at their pivotal points and the bolt lo serving as the pivot.

The lower ends of the handles project downward and forward from thepivot and are adjustably clamped or held against the opposite sides ofthe arch-brace by means of a removable pin or bolt Z, the arch-bracebeing provided with a series of holes to permit the pitch of the handlesto be readily varied.

It will be observed that the foot-bar b is beveled throughout its lengthto a V shape,

and that in a vertical central slot formed in its rear end is mounted acolter-blade m, this blade being pivoted at its forward end in the frontend of the slot and having its rear end extended a little beyond therear end of the stock and made adjustable in order that it may be raisedor lowered. The colter is rendered adjustable by means of a removablepin or key m passing through its rear end and engaging notches in therear edge of the stock on opposite sides of the colter, a series of thenotches being provided to permit of a series of adjustments. Theadvantage in beveling the foot-bar and attaching the colter thereto isthat the plow can be more easily handled and guided, the colter andbeveled edge entering the earth far enough to prevent swerving.

It will be evident that any style or pattern of plow-plate may be usedin connection with our improved stock. In. the drawings we have shown aplow of the double-sweep variety, the sweeps of which are set low inorder to lighten the draft. The plow is fastened to the standard by abolt n, which passes through the plow and standard, a series of holesbeing formed in the standard to permit the plow to be adjusted and toaccommodate plows of other sorts. The holes in the standard arepreferably made angular a part of their length, so that when but asingle fastening-bolt is employed the tendency of the plow-plate toshift sidewise is avoided. Riveted on the back of the plow-plate are twobars or plates 0, one being secured on each side of the standard andclose up to the same, whereby the plow-plate will be held steady andbraced. The bars 0 extend downward and afford a support for theremovable point p, which is bolted thereto. The bars 0 not only preventthe plow-plate from shifting sidewise, but also serve to strengthen thesweeps or moldboards.

It will be observed that an essential feature lies in the manner ofsupporting the beam, it being readily adjustable with respect to theplow-point, the plowman being enabled to vary the adjustment from hisposition at the rear of the plow. This providing for the adjusting ofthe pitch of the plow-beam is advantageous, since the plowman canreadily adapt the plow for different kinds of work and differentvarieties of plow-shovels.

The manner of supporting the handles is also advantageous, it being wellknown that the nearer the lower ends of the handles extend to theplow-point the greater will be the ease with which the plowman handlesthe plow, and mounting the handles pivotally on the stock enables themto be adjusted with respect to their pitch independently of the beam,which is an essential feature, especially in view of the fact that thebeam is made adj ustable.

The advantage in mounting the colter in the slot in the rear end of thefoot-bar and having the securing-notches in the rear edge of the bar isthat the liability of the colter getting fastened by reason of rust andclogging of dirt is reduced to a minimum.

Having thus fully described our invention, what we claim, and desire tosecure by Letters Patent, is-

1. The combination of a plow-stock, consisting essentially of a frontstandard a, a rear standard 0, upper connecting-bar d, and lowerconnecting-bar I), a pair of plates f being formed integral 011 theupper end of standard a, and a pair of separated plates h being formedintegral with the rear standard and projecting vertically therefrom,these plates being separated and provided with registerin g holes,aplow-beam pivotally mounted and fitted between the forward plates f,the rear end of said beam fittin g closely and working verticallybetween said plates h, a pin or bolt passing through the holes in theplates and engaging the beam, and a pair of handles supported on thestock independently of the beam, whereby the beam may be adjustedwithout varying the pitch of the handles.

2. The combination of a plow-stock, composed of a front standard CL,rear standard 0, upper connecting-bar cl, lower connecting or foot barZ) and a diagonal arch or brace a connecting the rear standard to saidupper bar (1, oppositely-projecting lugs j being formed on the upper endof the rear standard 0, a pair of handles pivoted respectively on saidlugs and having their forward ends extend down to said brace or arch,means for connecting the ends adjustably to said arch, and a beamsupported on the stock independently of the handle.

3. The combination of a plow-stock having a rearward-extending foot-bar,a colter-plate pivoted at its forward end and lying in a verticallongitudinal slot in the rear end of the foot, and a removable pincarried at the rear end of the colter-plate and engaging notches in therear edge of the foot-bar, substantially as described.

4. The combination of a plow-stock, a double-sweep plow attached to thestandard thereof, a pair of bars 0 attached to the rear side of theplow, one on each side of the standard, and extending downward andforward, and a removable plow-point bolted to the extended ends of saidbars, substantially as de scribed.

In testimony whereof we affix our signatures in presence of twowitnesses.
